2N6071A

Overview

The onsemi 2N6071A is a silicon bidirectional thyristor (Triac) designed for full-wave AC control applications. It features sensitive gate triggering compatible with TTL, HTL, CMOS, and operational amplifier logic functions. The device supports four-quadrant gate triggering and offers blocking voltages up to 600 V in the series. Key electrical parameters include an RMS on-state current of 4.0 A at TC = 85°C, a peak non-repetitive surge current of 30 A, and a peak repetitive off-state voltage of 200 V for the 2N6071A variant. It operates within a junction temperature range of -40°C to +110°C and utilizes a TO-225 package with thermopad construction.

Feature Summary

• Sensitive gate design uniquely compatible for direct coupling to TTL, HTL, CMOS, and operational amplifier integrated circuit logic functions.
• Four-mode gate triggering capability ensures reliable switching across all quadrants.
• Diffused and glass passivated junctions provide greater parameter uniformity and stability.
• Small, rugged thermopad construction enables low thermal resistance and high heat dissipation.

Applications

• Light dimmers
• Motor controls
• Heating controls
• Power supplies

Procurement Notes

Verify the specific ordering suffix to confirm packaging format and lead-free status. The standard 2N6071A is available in bulk boxes, while the 'T' suffix indicates tube packaging. The 'G' suffix denotes a lead-free package compliant with onsemi's soldering strategies. Confirm the required quantity matches the specified shipping unit, such as 500 units per box or 50 units per tube, to ensure proper handling and inventory management.

Selection Notes

Select the 2N6071A when a 200 V blocking voltage is sufficient for the application, distinguishing it from the 400 V (2N6073A) and 600 V (2N6075A) variants. Choose this component for circuits requiring direct interface with low-power logic gates due to its sensitive gate characteristics. Ensure the thermal design accommodates the 4.0 A RMS current rating and that the operating junction temperature remains within the specified -40°C to +110°C range for reliable performance.

Part Context

The 2N6071A belongs to the 2N6071A/B Series of preferred devices from onsemi. This series includes variants with different blocking voltage ratings, specifically the 2N6073A (400 V) and 2N6075A (600 V). All members share similar physical dimensions and thermal characteristics but are differentiated by their maximum repetitive off-state voltage capabilities, allowing designers to select the appropriate voltage rating for their specific AC control requirements.

Replacement Considerations

Direct substitutes within the same family include the 2N6073A and 2N6075A, provided the higher blocking voltages do not conflict with circuit design constraints. Verify that the replacement part maintains the same TO-225 package style and pinout configuration to ensure mechanical compatibility without PCB modifications.
